Title: Chromanoise suppressing method for video camera
Inventor: MATSUI SEIICHI
IPC: H04N9/68
Filed: 1993-11-19
Abstract: PURPOSE:To suppress the generation of chromanoise when performing photographing at low illuminance. CONSTITUTION:An image pickup signal S corresponding to an optical image formed by a lens 1 passing through an iris 2 is outputted from a CCD 3, and at the time of low illuminance, the image pickup signal S is amplified by an AGC circuit 5. A Y/C separating circuit 6 performs filtering to the image pickup signal S and outputs a luminance signal Y and color synthesizing signals Cr and Cb. At low-illuminance photographing, a chrominance signal processing circuit 20 respectively adds offset alpha to respective primary color signals R, G and B provided by matrix arithmetic at a matrix arithmetic circuit 21, by using an offset adding circuit 22. Thus, a gamma correcting circuit 23 performs correction to primary color signals R+alpha, G+alpha and B+alpha with offset, and color difference signals R-Y and B-Y are formed by a chrominance signal processing circuit 24.

Title: Switching regulator
Inventor: SAKAI SETSUO
IPC: H02M3/155
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a high-voltage large-capacity output by setting switching elements which were sequentially turned on, to a turned off state, after the elapse of a predetermined period, sequentially turning them on whenever the next clock pulse rises, and superimposing the magnetic energy accumulated in a plurality of inductances. SOLUTION: A control circuit 15 performs on-off control of four FETs 10 to 13 based on the changes in the terminal voltage of a load 16, and if the voltage of the load 16 becomes lower than the predetermined voltage, then on-time of the FETs 10 to 13 is extended, thereby increasing energy accumulating time of the inductances 2 to 5 is increased and obtaining a higher output voltage. Also, if it becomes higher than the predetermined voltage, on-time is reduced, so that a low output voltage can be obtained. Then regardless of the fluctuations in the load 16, the output voltage is always held constant, inductances 2 to 5 are repeatedly operated in on-period, accumulated magnetic energy is superimposed, and the load 16 is driven. In this way, a high-voltage, large-capacity output can be obtained.

Abstract: PURPOSE:To simplify the installation work for the apparatus and at the same time prevent the noises that develop in the closing of a second check valve when the closing valve is closed by limiting the volume of a gas-liquid separator in a specified range and providing the second check valve at a specified location. CONSTITUTION:Because the volume of a gas-liquid separator 3 is larger than the volume of a liquid coolant into which the difference of the amounts of filling of the coolant into the largest length of connecting pipings 7 and 8 to the outlet and inlet ports of a radiator 6 and into the shortest length of them is converted, if the pipings 7 and 8 are changed to the shortest connecting pipings with the amount of the coolant filling in the longest connecting pipings, the liquid surface in the gas-liquid separator 3 changes between 12A and 13B, and because the difference in the amounts of the coolant due to the difference in the lengths of the pipings 7 and 8 can be absorbed by the difference in the liquid surfaces in the gas-liquid separator 3, the adjustment of the amount of the coolant for the difference in the lengths of the pipings 7 and 8 becomes unnecessary at the time of executing the construction work for the device. Further, because a second check valve 5 is provided at a position which is always the gas section when a closing valve 4 is shifted from opening to closing during the pipings 7 and 8 are the shortest, it is possible to prevent the noises produced when closing the second check valve 5 while the closing valve 4 is closed.

Filed: 1992-10-06
Abstract: PURPOSE:To prevent a valve element and a valve seat from damage caused by the overrun of a motor by interposing a coil spring as a cushion body between pressing force adjustment mechanism and a movable valve element by positioning the movable valve element of a hot/cold water mixing valve by the balance of two coil springs. CONSTITUTION:The movable valve element 114 of the hot/cold water mixing valve of a hot/cold water mixing device is positioned by the balance of the two coil springs 132 and 134. The pressing force of the coil spring 134 is adjusted by the pressing force adjustment mechanism 46. The coil spring 134 operating as the cushion body is interposed between the pressing force adjustment mechanism 46 and the movable valve element 114 so as not to apply excessive force to the movable valve element 114 and the valve sheets 120 and 122 even when the motor 144 of the pressing force adjustment mechanism 46 overruns. The pressure of hot water provided for a mixing valve 22 is reduced by pressure reducing valves 14 and 18 to minimize the influence of transient pressure fluctuation in spite of adopting the structure of positioning the movable valve element 114 by the balance of the two coil springs 132 and 134.

Title: Thread servo circuit for optical player

IPC: G11B21/10
Filed: 1986-12-10
Abstract: PURPOSE:To decrease the reading errors of the recorded data by having constitution to output the PWM pulse width modulation signal to be supplied to a drive output means only for a period of the reproduced address signal of an optical player. CONSTITUTION:A waveform B showing the address area of an optical disk is supplied to a sawtooth wave generating circuit 3A and a triangular wave signal form C is produced synchronously with the signal waveform B. The waveform C is compared with a servo signal waveform A by a comparator 3B for output of a PWM signal waveform D. That is, the waveform D is outputted only when a spot radiated onto the optical disk is kept in the address area and not outputted for a period when the information is read on a photomagnetic surface. Thus it is possible to prevent such a case where the noise in mixed into the reproduced RF signal of a recorded area due to the intermittent waveform D.

Abstract: PURPOSE:To constitute a PLL circuit without any low-pass filter and, at the same time, to secure the capture range of the PLL in a narrow state by realizing a constitution which controls the frequency dividing ratio of a variable frequency dividing circuit by using the output signal of a D-FF. CONSTITUTION:When the phase shifting of the 2nd output signal (b) of a variable frequency dividing circuit 7 goes faster by >=90 deg. than input signals (a) impressed upon an input terminal 5, the output signal of the 1st multiplier circuit 8 becomes the signal (c).

Title: Superconducting power source
Inventor: YUZURIHARA HAJIME
IPC: H01F6/00
Filed: 1987-11-18
Abstract: PURPOSE:To obtain a superconducting power source which utilizes Meissner effect as one of the superconductivity of a superconducting material by employing a current flowing due to the Meissner effect of a crystalline film by approaching a permanent magnet to the film set to its critical temperature or lower. CONSTITUTION:A ringlike crystalline film 2 made of a superconducting material is manufactured on a substrate 1. A disc-shaped permanent magnet 3 is disposed fixedly to a magnet securing frame 4 above the film 2. The film 2 is not formed in a closed ring, and a pair of current paths 5 are integrally formed from the parts of the film 2. The frame 4 is formed of insulating substance, such as plastic or the like, and is so secured as to give the magnet 3 a small play. When the magnet 3 is approached to the film 2 while cooling the film to its critical temperature or lower, Meissner effect which tends to disturb a magnetic flux is generated in the film. As a result, a diamagnetic current flows. This current permanently continuously flows due to its zero resistance.
